PLAITER FOR SEWING-MACHINES.

ZZPECZFIGATIOIQ' forming part of Letters Patent No. 306,743, dated October 21, 1884.

Application filed November 5, 1883. (110(lcl.)

To all whom it may concern:

Be it known that I, JOHN M. Gnrns'r, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Plaiters for Sewing-Machines, of whiehthe following, in connection with the accompanying drawings, is a specification.

In the drawings, Figure 1 is a top view plaiter embodying my improvements, and shown as attached to the machine. Fig. 2 is an edge view of the same. Fig. 3 is a top view, in detail, of a part. of the holder. Fig. is an edge view thereof. Fig. 5 is atop view of the upper set or group of parts. Fig. 6 is alike representation of the lower set or group. Fig. 7 is a bottom viewof the upper group, and Fig. 8 is an edge view of thelower group.

Like letters of reference indicate like parts.

My invention relates to a class of plaiters an example of which is shown and described ofa ' in Letters Patent of the United States of America No. 268,398, granted to me the 5th day of December, 1882.

A represents the cloth-plate of a sewingmachine; B, the serrated feed-plate; C, the presser-foot bar, D, the needle; E and F, the shuttlerace slides, and G the throatplate.

II is the presser-foot, and H is a screw entel-ing its horizontal part.

I is a horn-plate, and I is its horn or folder.

This plate consists of two longitudinal arms,

a and a, connected by means of a cross-bar or arm, a. The arm ais bent or raised slightly, as indicated, to bring a portion of the arm a somewhat higher than the arm a, and the horn end of the arm a is bent downward and back, as shown, and is also inclined slightly, as shown at b. A bridge, 0, having a widened or enlarged central part, c, in which is an opening, 0, is raised near the free end of the arm a, and cis a notch or openingin the same portion of the said arm.

(Z (l are lugs extending upward from the said arm, and c e are holes in the arm a.

J is a rectangular slide having a depending part, f. This slide serves, as an adjustable gage, and moves between the bridge 0 and the lugs d (2, and is overlapped by the part c.

K is a sliding or adj ustable scroll-plate, and K is its scroll. The arm a passes freely through the scroll K, and one arm of the plate K passes between the bridge 0 and the inner lugs, (Z d, and is overlapped by the parts 0. The upper group of parts I attach to thepresser-foot by withdrawing the gage J, raising the screw H, passing the enlargements 0 underneath the head of the said screw, replacing the said gage,and tightening or screwing downthe said screw upon the said enlargement, thereby retaining the plate I, plate K, and gage J together upon the presscr-foot, and rendering it unnecessary to remove the screw H for the purpose of applying and removing the upper group of parts and setting the gage and scroll-- Lateral or torsional movement of the plate. parts applied to the presscr-foot is prevented by means of studs 0' c, projecting from the presser-foot into the holes 6 e, and these studs and holes also cause the said parts to be set accurately on the presser-foot. The said parts may also be applied and removed with ease.

L is a horned plate belonging to the lower group of parts, and L is its horn or folder.

M is a rack or serrated portion raised from the long arm of the plate L.

N is a holder or baseplate for holding the plate L properly in place upon the cloth-plate of the machine. This plate or holder is a frame-like structure, and g g are lugs depend ing therefrom. A tongue, 71, also projects from one arm or bar of the holder N, and eX- tends horizontally in a plane somewhat below the main part or body of the holder, as indicated in Fig. 1. The long arm of the plate L passes freely through slots in upturned ends or corners of the holder, as indicated at z 2'.

O is a spring lever or catch, through which the long arm of the plate L also passes freely. One end of the lever 0 also passes through one of the slots i 1', as indicated, and that end has upon it small upraised projections or catches I is a scroll, Q a presser, and It a lug, all

formed on one arm of the holder N.

To attach the plate L to the holder N, I pass the long arm of that plate through the slots i *5, and turn the lug It down over the short arm 'ol' the said plate, but not tightly enough to bind it.

To apply the lower group of parts to the machine, I draw out the plate E to about the position indicated by the dotted lines at 7C, Fig. l, and then arrange the holder in the opening thus made, the lugs g g and the tongue It being downward. I then push back the plate I!) over the tongue 7:. and against the lugs r r when theholdcr will be firmly held in its proper place. The presser Q, then rests on the serrated icedplate. By this means the lower group may be quickly and accurately applied to the machine, and may also be removed with facility.

To adjust the parts for work, I proceed as follows: It the tucks are to be, for example, one-quarter of an inch wide, I set the lever O on the rack X so that the lever, when depressed, will engage the rack one-quarter of an inch. from the right-hand end of the latter. I then depress the lever and draw it, together with the plate L, to the extreme left until the horn ll comes in contact with the lug It, as indicated in Figs. 1 and 2. I then lower the upper group and move the lever O, with the plate L, until the raised parts j j err gage the holder N, after which the scroll K is moved up to within about a thirty-second of an inch of the horn L, and the gage J is set as heretofore and as described in the said Let tors Patent. It" the screw ll. be now tightened, all the parts in the upper group will be held firmly together. I now move the lever O and plate L to the extreme left and raise the presser-foot. The material orgoods are placed between the upper and lower groups, the horn or folder I depressed by the forefinger ofthe right hand, while the lower horned plate or folder is moved to the right until the lever O engages the holder N, when the fold will be formed. The gage 1' extends forward of the fixed holder orhorn and of the needle, and pro jeets between the upper horned plate and the long arm of the lower horned plate. The material passes over the latter plate and under the gage, and is held up to it and retained against it without being in cont-act with any part underneath the goods, thus avoiding friet-ion and the retarding of the movements of the goods. The scroll K has its portion 13'. rated over thehorned arm in the upper group, and the arm a of the plate I passes freely through the bent or depending end ofthe plate K, thus bringing the scroll proper between the upper and lower portions of the arm a, thus holding them together. The presser Q, by reason ofits contact with the serrated feedplate, causes the lower or fixed scroll to rise and fall simultaneously with the upper group of parts, so that the upper and lower parts will be prevented from coming together and interfering with the free passage of the goods through and around the scrolls and folders. The lower scroll is also so connected to the plate L that the said scroll and plate have the same vertical or yielding action, and the lug ll, by so holding these parts together, prevents them from. being separated by means of scams or otherwise, thusavoiding the improper passage of the goods between the parts so held together. I

It will be perceived from the foregoing description, and on reference to the accompanying drawings, as well as to the Letters Patent hereinbefore referred to, that the principal diffcrences between my present and my said former invention relate to the means employed for attachin g the upper group of parts to the presser-loot, for attaching the lower group to the cloth-plate, for adjusting the parts with reference to the width of the folds, for withdrawing the horn or folderin the lower group from the fold, and for gaging the folds.

I do not here claim the holder N, broadly or independently, when constructed substantially as herein shown and described, having made claim thereto in a pending ap )lication, No. 110,865, for a patent for improvement in holders for sewinganachine attachments.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
